Ah. OK. Anyway this is not a Unicode problem. PDF knows nothing about unicode. It uses the encoding of the fonts used. The ti ligature is a glyph in the font used in that document. Its code has nothing to do with anything unicode. It looks like a pre-unicode hack because unicode says nothing about font technologies, and hence nothing has changed in PDF because of unicode (nor could have, unicode does not mandate how to encode ligatures).
